The bug exploited just how the dating service used Facebook’s Account Kit to permit its users to login through their telephone numbers. However, hackers might have used this “convenience” to hack into Tinder accounts using just the contact number of your target.

Facebook explains its Account Kit like a service that may be helpful to let “people quickly use and login towards your app by employing just their cellular phone number or current email address – no password needed.” As part of his latest bug discovery,?Anand Prakash reported the Tinder API wasn’t checking you ID around the token made available from Account Kit through the login process – a flaw which could have already been exploited by attackers to make use of any other app’s access token to take over Tinder accounts.
